To enable a proposed subsea transmission cable from Shetland to connect to the UK National Grid, we are proposing to construct an HVDC switching station north of Wick in Caithness.
We have developed and successfully gained an outline planning permission to construct an HVDC Switching Station which will connect to the HVDC system that is currently being installed between Caithness and Moray. This arrangement makes use of capacity available in the Caithness-Moray subsea cable to allow onward connection to the existing onshore transmission network in Moray with minimum new infrastructure.
The switching station will allow the flow of electricity to be managed between three underground HVDC circuits - one from a converter station at Spittal in Caithness, one from a converter station at Kergord in Shetland and one to a converter station at Blackhillock in Moray.
We are required to develop proposals to accommodate new sources of electricity generation seeking to connect to our network. In response to generators seeking to connect in Shetland, we are proposing to install a new High Voltage Direct Current (HVDC) transmission cable which would connect the islands to the Great Britain electricity system for the first time. HVDC technology makes it possible to transmit electricity efficiently across the distances involved in connecting Shetland, which is located about 170 kilometres north of mainland Scotland.
